To all whom t may concern.'

Be it known that I, VILLIAM C. BAXTER, citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Rounding Soles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will 1 type which are employed for trimming the ed e of the sole at thel heel seat.

. ne object ofthe present invention is to provide an improved machine of this type which trims the edge of the sole evenly and uniformly without marring or otherwise defacing the' upper of the shoe or the project' in@ margin of the sole.

In addition to trimmingthe edge ofthe sole at the heel seat, it is often desiredftobevel the projecting margin of'this portion of the sole. In this operation as generally performed, substantially the entire surface ex'- tending from the junction of the 'sole and counter of the shoe to. the edge of the sole is beveled or randed. Asthe width of the projecting margin varies with different styles and sizes of shoes, it is desirable to arrange the randing mechanism so that all soles are randed uniformly without necessitatingA a separate adjustment. of the randing knife.

A .further object of'theinvention is to pro vide a mechanism for randing soles uniformly which does not require an adjustment for ope-ration upon extension edges of varying Widths.

Vith the above objects in view, the several features' of the invention consists in certain l Figure 1. represents a side elevation partly y in section of a machine embodying the -several'features of the invention in their preferred form; Fig. 2 isla detail illustrating a partial front elevation of the machine shown in Fig. l; Fig. 3 is a detail showing a partial side elevation of the machine and illustrating the crease guide, and upper feed wheel in section; and Fig. 4 is a view partially diagrammatic illustrating the relative transverse positions of the randing knife and crease guide.

The machine shown in the illust-rated embodiment of the invention comprises a standard 1 supporting a head 2 in which is jour- 65 naled a drive shaft 3 carrying a tight pulley 4 and a loose pulley 5 thereon. A suitable belt shifter indlcated at 7 is slidingly mounted upon the head of the machine and serves to change the belt from the loose to the tight pulley, or vice versa. The drive shaft 3 is operatively connected with a feed shaft 9 through a pair of intermeshing spur gears 10 and 11. A second feed shaft 12 is journaled in the frame of the machine above the feed shaft 9 and is driven by intermeshing gears 13 and 14 mounted upon the shafts 9 land 12 respectively. The outerY ends of the;l

two shafts carry feed Wheels indicated at 15 and 16 whichy engage and grip t-he edge 80 of the sole between them to feed the shoe. TheA feed Wheels are separated to allow the shoe to be readily inserted in or withdrawnl from the machine and 'this is accomplished by mounting thev lower feed wheel in a slide 17 which isfvertically movable in the head 2. The feed wheels are normally forced together by a spring 18 which loosely embraces the slide 17 and is interposed between a shoulder formed upon the slide and a stud determine the Working position of the lower feed wheel. With this construction and arrangement, it is obvious that both th'e`compression of the spring 18 and the normal position ofr the feed wheel may be varied either independently or in unison. In order to compensate for vertical movements of the slide 17, the feed Wheel is secured upon the outer end of a short shaft 21' journaled in ways commence at the same distance from the counter of the shoe independcntiy of vany adjustment which is made to Avary the vWidtivof the extension edge.-

' of the invention.

Having thus described the invention', what is claimed is:

l. A machine for trimming ythe soies of boots and shoes having, in combination, a trimming knife, a guide positioned adjacent to the knife for determining theline of cut made by the knife, and a pair of feed members engaging the sole upon opposite sides of the knife with a greater degree of fee-ding action upon the outside of the line of cut than upon the inside, substantially as described.

2. A machine Vfor .trimming the soles of boots and shoes having, in combinatioina trimming knife, a guide positioned adjacent to the knife for determining the line of cut made by the knife, a feed member engaging the sole inside of the line of cut made by the knife and arranged to guide and feed the sole without entering into and marring the surface, and a feed member engaging the sole outside of the line of cut and arranged .to dig into and positively grip the sole to feed the same, substantially as described.

A-machin'e'for trimming the soles of boots and shoes having, in combination, a positioned adjacent to the knife for determining the line of cut made by the knife, a pair of feedJ wheels enpositively grip the sole,

gaglng the sole upon opposite sides of the knife inside and outside of the line of cut and provided respectively with a periphery arranged to frictionaliy enofage the sole and with a series of `.coarse teeth to dig into and substantially as described.

t. 'A machine for trimming the soles of boots and lshoes having, in combination, a trimming knife, a guide for the shoe, and a pair of feed wheels positioned in'close proximity to one another above and below the knife, each feed wheel having an annular groove formed in its periphery in which the knife is received, described.

5. A machine for trimming the soles of boots and shoes having, in combination, a guide for the shoe, a plurality of pairs of it will be understood .f the.` feed wheels,

substantially as y feed 'wheels engaging the top and bottom ofV the sole constructed and arranged to provide a recess between the Wheels of each pair, and a trimming knife having its cutting edge positionedbetwe'en the upper and lower feed wheels received in said recess, substan- 4ti'allyas described. y

6. A machine for trimming the soles of boots and shoes, having, in combination, a pair of upper and iow'er 'coperating feed wheels, atrimming knife positioned between a crease guide having provision for a Vtransverse adjustment relative to trimming knife, and a randing knife mounted upon the crease guide and adjustable therewith, substantially as described.

7. A machine for trimming the soles of 'boots and sh'oes having, in combination, a pair of upper and lower cooperating feed wheels, a trimming knife supported between the feed wheels, vision for atransverse adjust-ment relative to the trimming knife, a randing knife mounted upon the crease guide, and having provision for adjustment relative to the crease guide, substantially as described.-

l8. A machine for trimming the soles of boots and shoes having', in combination, a trimming.' knife, a pair offeed wheels arranged to engage the Vsolcon opposite sides a crease guide having proof the line of cut above and below the trimming knife,'and a stationary crease guide supported adjacent to the trimming knife and arranged to determine the line of cut made by` the knife, substantially as described.

9. A machine for trimming the soles of boots and shoes4 having, in combination,

means for feeding the shoe, a crease guide,

and a randing knife supported in close proximity to the crease guide and having provision for adjustment to and from the guide both in the line of feed and transversely of the line of feed, substantially as described.

10. A machine for trimming the soles of boots. and shoes having, in combination,

vmeans for feeding the shoe, a .crease guide,

and a randing knife supported in close proximity vto the crease guide and having provision for a vertical adjustment and' horizontal adjustments to and from the Vknife both in the line of feed and transversely of the line of feed, lsubstantially as described.
